Title: Keyboard device
Inventor: IWASAKI TOSHIROU
IPC: H04L29/12
Filed: 1983-08-10
Abstract: PURPOSE:To definite the input to the computer by converting a status signal of an analog touch key into a signal similar to a normal key input signal and transmitting the signal corresponding to the analog touch key to the computer by a serial transmission line in common to a normal key. CONSTITUTION:In depressing a key of a conventional keyboard section, an H level signal is outputted from a matrix circuit 21 for the period and fed to a pulse generating circuit 23. The circuit 23 detects the rise of a signal and generates a pulse signal having a time width and gives a signal to a P-S converting circuit 27 via an OR circuit 25. On the other hand, when a key in an analog touch key section inputs a signal, an H-level signal is fed from a matrix circuit 21 to a pulse generating circuit 24 by the corresponding time. The circuit 24 receives it, and transmits a prescribed pulse signal having a prescribed time width and synchronized with the rise/fall time of the signal to the circuit 27 via the circuit 25, and the circuit 27 forms a discriminating bit representing the pulse synchronized with, e.g., the rise and transmits (4) it.

Title: Heating cooker
Inventor: ISHIHARA MASAHIRO
IPC: G01N21/84
Filed: 1979-11-14
Abstract: PURPOSE: To attain stable, excellent operation of a heating cooker in which food scorching operation is carried out automatically through detection of the change in the relfection factor on the surface of a substance to be heated with heating of said substance by means of a light sensor, by protecting the light sensor with a transparent glass equipped with a means for combusting and removing products resulting from heating of said substance.  
     CONSTITUTION: When current is supplied to electric heaters 5aW5d from a power source 24 with food 3 being placed on a table 2, a lamp 9 is lighted and visible rays  are irradiated onto food 3 through glass windows 14a, 14b. At the same time, a fan  19 is set into operation. When the surface of food 3 begins to scorch with heating of  food 3, intensity of light reflected off the surface of food 3, detected by a light  sensor 11, drops gradually. When the intensity of reflected light is lowered to a predetermined level, food scorching process is finished by a control means 26. Here, if  products resulting from heating of food 3 are attached to the surface of glass 14a  and its transparency is lowered, the tranaparency can be kept constant by supplying  current to a pattern 1 of resistance heater attached to the back surface of glass 14a  and thereby removing the products by way of combustion of the same.

Abstract: PURPOSE:To realize the miniaturization of a transformer with a reduction of cost  for a power supply device having an output transformer in a stati variable frequency power supply device, by providing a starting switch at the load side of an output transformer. CONSTITUTION:A starting switch SW is provided in series at the load side of an output transformer Tr, and this switch is opened before the starting to turn on either thyristor CR1 or CR2. Then the transformer Tr is deflectively magnetized to the positive or negative polarity. Under such conditions, the CR1 or CR2 which is in an on-state is turned off, and the switch SW is applied to start the operation by an ON control of the CR2 or CR1 that magnetizes the Tr in the opposite direction to the deflective magnetization. Accordingly the current can be continously flowed for a period of time twice as long as the time required when the starting is given without any deflective magnetization carried out for an iron core. As a result, the sectional area of the iron core can be reduced down to a half.
